Application. filed June 24, 1920. Serial No. 391,287.

T 0 all whom it may concern:

Be it known that I, CHARLES E. SAGE, a

citizen of the United States, and resident of ready attachment to the end of the well casing for. the purpose of closing the casing quickly in the event of the striking of a gusher, an object of this invention being to provide a simple and durable construction which maybe quickly adjusted to effectively close the ripper end of the casing tube.

To this-and other ends, the invention consists of certain parts and combinations of parts all of which will be hereinafter dering.

Referring more particularly to the drawscribed, the novel features being pointed out in the appended claims.

In the drawings; r Figure 1 is a view partially in section showing the casing head in elevation connected to the upper end of a casing tube;

Fig. 2 is .a vertical section on the line 7 Fig. 3 is aplan view of the casing head with parts in section; I

Fig.- 4 is a section on the line 4-4, Fig. 2; Fig.5 is a .plan view partially in section of the packing ring; and v Fig. 6 is an edgeview of the packing ings, 1 indicates the casing tube which is I externally threaded at 2 at its upper end.

On this externally threaded end is arranged a packing ring 3 preferably formed of soft metal such as soft steel and having its periphery beveled at opposite sides at 4. This ring is internallythreaded at 5 to engagg the t is preferred also to make this ring in two sections, the sections being preferably'connected together by two links 6, the links being secured to the ring sections at 7 and being received in the pockets 8 formed in the periphery of the ring adjacent the joints between the sections.

The upper end of the casing tube is pref erably held between two I beams 9 which ing curved and engaging the opposite sides of the casing tube 1'. These blocks are removable to permit casing tubes of different diameters to be clamped. Tie-bolts 12 secure the I-beams together and in firm engagement with the casing tube 1, the outer tie-bolts 12 having tubes 13 surrounding them and acting to space the outer ends of the I beams apart. The casing tube with the packing ring projects above these I beams. I

The casing headis formed, in this instance, of two sections 14 and 15, the head being divided in the direction of the casing 2 to provide such sections. \Vhen the sections are associated together, a passageway p through the head is provided which extends in the d rection of the longitudinal axis of the casing 1. The sections are preferably held together by bolts or rods 16 which are threaded at opposite ends as at 17 and 18.

"The threaded ends 17 are secured in the member 14 so that the bolts or rods project beams or are separated and are supported on the I beams 9, such I beams acting as guides in order to direct the members 14 and15 into cooperation. This guiding is preferably secured by providing the lower ends of the casing members 14 and 15 with guiding hooks 20 at the lower portions of said members, these guiding hooks traveling on the uppermost flanges of the I-beams. The inner faces of the members adjacent their guiding hooks are provided with groove segments 21 which when together form an annular groove at the lower end of the passageway through the casing head. The upper and lower walls of this groove are beveled and cooperate with the beveled edges 4 ofthe ring 3 in order that when the sections are drawn together, the perimeter of the ring 3 will be compressed and 'a'tight joint between the ring and the casing head will be established. The-member 15 may be provided with a lateral port 22 from which a piping may lead to conduct oil to any suitable point, whereas the member 14 is provided with a valve member 23 operable through a stem 24 in a well known manner. may be moved to a position where the pas- This valve member I so packing ring 3 has its periphery brought 40 v 3 taken from the head at this point. i

' What I claim as my invention and desire sageway through the casing head will be opened and 'may also bemoved to 006perate with divided valve seats 25 formed on the two casing sections 14; and- During drilling the members 14 and 15- mayeither be supported in separated positions on the I beams 9 or may be removed therefrom. The dividing packing ring is ing has a diameter corresponding to the formed: with anexternal diameter corresponding to the internal diameter of the casing head members while its central opendiameter of the casing. It is apparent this construction permits the use of the head with casing tubes of different diameters merely by usingthe packingrings which 'have central openings corresponding to the I diameter of the casing tubing. The packing ring may either be secured to the casing tubing during the drilling or may be separated from the-casing tubing to be fitted thereto when a gusher is struck.

In attaching the casing head, the casing" members are moved together on the I beams 9, the members 15 being guided toward the member 14 the rods or bolts 16. The nuts 19 are then quickly secured to the screw'threaded ends 18 of the'bolts so -as to draw the members 14 and 15.1;0gether.

As these members are brought together, the

i in firm engagement with the walls of the .members 14 and 15 so-thata liquid tight joint is provided betweenthe casing tube and the casing head. After the casing memvbers are secured together, the valve-'23 is. closed, thus directing the oil through the v 'port 22. If it is desired later, a pipe may "be connected to the. flanged upper 'end 26 of theoasing headandthe oil may be also to secure by Letters Patent is:

1. An. oil well controller comprising, 'in" combination with a wellcasing, a pair of beams supported on opposite sides of the 'casi'ng' below the upper ends thereof, blocks secured to the inner facesrof said beams and having their inner ends engaging the well casing on opposite sides, tie bolts connect ing said beams'togeth'er, and a casing head having a passageway in line with the cas ing and divided longitudinally of the casing into two parts, each of which is guided on the beams. v

2. An oil well controller comprising, in

combination with a well casing, a pair of v beams supported on opposite sides of the casing below the upper end thereof, means for tying and spaclng said beams, a casingheadhaving a. passageway in line with the casingand divided longitudinally of the casing into two'sections each of which has its lower end guided on the two beams, and a packing ring secured to the pro ect1ng portion of the well casing and adapted to be engaged by the two sections of the casing head. I p

3. An oil well controller comprising, in

combinationwvith. a well casing, a pair 'of beams supported on opposite sides of the .casing below the upper end thereof, blocks 'beams, and a packing ring interposed between the projecting end of the well casing and the casing head. f .4. An oil well controller comprising, combinationv with a well casing, a packing ring of soft metal having screw threaded engagement with the upper end of the well,

casing, and a casing head dividedin the direction of the length of the wellcasing and having a passageway in line with said well casing with an internal gro'ove'in the walls thereof formedto compress the perimeterof the packing ring when the two 'members of the'casing head are secured to gather.
